Why should I have to waste my time and duct tape on their shitty scam? :) Easier to just never stay at a Hyatt.

Duct tape adhesives (including polyterpene resin) might register as VOCs. Now, if you duct taped a piece of absolutely clean aluminum foil to it, then that could be fine.

I'd take the opposite approach, put something in the room that continually triggers it so they keep coming up and then just ignore it eventually.

I have seen tradies attempt to ‘disable’ smoke particle detectors by putting tape or a rubber glove over the sensor. This technique often triggers the alarm almost immediately.

Commercial fire sensors do have plastic caps which block airflow without triggering an alarm. They’re designed to be kept on during construction until each sensor is commissioned.

"Fire Safety Device Interference Fee: $1,000"

IANAL - but might doing that sift the burden of proof, and force Hyatt to show that the Rest device met regulatory standards as a fire detector?

I bet there are standards about this, and I’d also bet Rest has optimized their product for stealing money, not safety.
